Never trust anyone who says you won something. Don't connect your wallet to the fake pancake swap or any other shady website. Only use the contract address straight from the real website, yes, Never store your seed phrases in your phone. Turn off dapps, make sure you disconnect your wallet from pancake swap after you are done using it. Never sell or send coins that just show up in your wallet.
My opinion is that a trader should bring more knowledge about how to ensure the security of his wallets than he would like to gain knowledge about the market before coming to trade in the market. Because no matter how much a trader is an expert in market research, if he has no knowledge about the security of his own trading account, wallet, then his achievements can easily be lost and fall into the trap of scammers. So your advice is important for a trader, because a wrong decision can be a scam for a trader after seeing a lucrative offer.
I guess once you become a trader, you are already responsible on the security of your account or wallet. Otherwise, everything you put an effort to win your trades will just go to waste. So as much as possible, always secure your account by keeping it secret from the people around you. Except your family members because they can be trusted for sure. However, sharing or intending to brag what you achieve is never a good option. Chose to be a lowkey person and everything will be put in its right place.
